My first pistol to date. So the CQB isn't offically my next weapon, but I am impulsive. I had an idea for making a spinning chamber and I ended making this gun in 1 day!
Working:
trigger
hammer
spinning chamber
and the chamber moves in and out to load the bullets

The chamber moved out with loaded bullets

The hammer realaxed

the hammer pushed back. Note: the stupid green rubberband is the only thing that holds the other rubberband in place. Also the trigger and the hammer work on the same rubberband!
